A central guide to the v2rayN desktop client, the v2rayNG Android client, and subscription configuration. Import the same server parameters on each platform, then configure the system proxy, TUN interception, and routing rules separately.
Client configuration is more than a single switch. Subscription updates, protocol parameters, proxy modes, and routing rules form one continuous chain. Understanding these steps in connection order makes it easier to pinpoint problems during troubleshooting.
A subscription URL delivers server entries, while the client writes them into a local group. After the first import, run a subscription update manually, then check whether selectable nodes appear in the server list. Review the group name, update result, and log messages together; a single new row in the interface is not enough to confirm success. For long-term use, split groups by service source so identically named nodes from different subscriptions do not get mixed together. Keeping manual settings before an update also makes overwrite relationships easier to assess.
This workflow applies to both v2rayN and v2rayNG, but menu locations and system permissions differ. Desktop clients are better suited to managing multiple configuration groups, while Android also requires confirmation of background operation and network interception permissions.
Protocols such as VLESS, VMess, and Trojan define only part of the connection path. The address, port, user identifier, security layer, transport, server name, and flow parameters must match the server field by field. With VLESS and REALITY, for example, the client must also verify the public key, short ID, fingerprint, and target name. Any mismatch can appear as a handshake failure or a connection that cannot exchange data. Subscription imports reduce manual entry, but understanding how the fields relate remains essential for reading logs and migrating configurations.
These documents use the actual field names to explain configuration structures rather than replacing key parameters with unclear abbreviations. For sensitive credentials, they describe only each field’s purpose and entry requirements.
The routing module decides whether a request uses the proxy, connects directly, or is blocked. Rules are usually matched from top to bottom, so private addresses, specified domains, geographic data sets, and fallback rules need a clear order. Domain strategies also affect how rules translate between domain names and addresses, so they should not be adjusted separately from DNS settings. For ordinary use, start with the client’s basic split-routing template, then add a small number of high-priority rules for fixed services. This is easier to maintain than importing a large set of unknown rules at once.
When access results differ from expectations, record the target domain, the matched rule, and the final outbound path. This helps distinguish node connection issues from DNS resolution and rule-order problems.
The system proxy primarily handles applications that follow the operating system’s proxy settings, making it simple and suitable for browsers and common desktop software. TUN mode uses a virtual network interface to handle a broader range of traffic, including programs that ignore system proxy settings, but it requires additional permissions and coordination with the local firewall, virtual adapter, and DNS setup. More interception is not always better: validate the connection with one method first, then decide whether to switch based on application coverage to avoid duplicate interception and loopback paths.
Before closing the client, restore the related system state. If the network behaves abnormally after a restart, first check whether the system proxy remains enabled, whether the TUN interface is still active, and whether another program is using the local port.
Use v2rayN on desktop platforms, v2rayNG as the primary choice on Android, and v2flyNG as an alternative based on a different kernel family. Each platform link opens the corresponding tab on the downloads page.
Windows users can choose between the desktop edition and the classic WPF edition. The desktop edition follows a cross-platform interface approach for users who want a consistent workflow; the WPF edition retains the traditional Windows interface and established usage patterns. After installation, import the subscription, update the group, select an active server, and enable the system proxy.
Go to Windows downloadsmacOS packages are separated by processor architecture. Choose arm64 for Apple Silicon devices and x64 for Intel-based Macs. The first launch requires system permission approval; enabling TUN also requires allowing the relevant network-extension operations. Start by validating the subscription and node with the system proxy, then enable broader traffic interception only if the application coverage calls for it.
Go to macOS downloadsv2rayNG is the primary choice on Android and follows the Xray kernel line, supporting common VLESS, REALITY, VMess, and Trojan configurations. Most modern devices can use an arm64 build; when the architecture is unknown, use the universal build. After importing a subscription, grant network interception permission in the system connection confirmation screen and adjust background restrictions according to the device’s battery policy.
Go to Android downloadsThe v2rayN desktop client on Linux supports deb and rpm packages according to the distribution’s packaging system, with separate x64 and arm64 builds. The graphical client handles subscriptions, server lists, and routing settings, while system-tray behavior may vary slightly across desktop environments. Before enabling the system proxy, confirm which proxy source the desktop environment reads to avoid changing only one layer of settings.
Go to Linux downloadsThe client interface and network kernel have different responsibilities. Understanding this relationship helps identify where protocol capabilities come from, which layer to troubleshoot when configuration fails, and why features can differ between clients.
Project V has grown into an open technical ecosystem around proxy protocols, transports, routing rules, and configuration models. It is not the name of a single graphical interface, nor is it synonymous with one network kernel. The server lists, subscription groups, system proxy switches, and log windows seen in a client belong to the interaction layer. The underlying kernel performs connection establishment, protocol handshakes, data forwarding, and route matching.
This separation lets interface development and protocol implementation evolve independently. Graphical clients can improve platform integration, configuration management, and workflows, while kernel projects handle protocol compatibility, transport details, DNS behavior, and route execution. When problems arise, first determine whether they originate in subscription data, the client interface, operating-system interception, or the kernel connection layer; this is more effective than repeatedly switching nodes.
V2Fly extends V2Ray’s configuration model and protocol ecosystem, covering core modules such as proxy inbounds, outbounds, transports, DNS, and routing. v2flyNG follows this kernel line as an alternative Android client. Choose it according to the server’s actual protocol and parameters, rather than judging compatibility from the client name alone.
Xray shares many configuration concepts with the Project V ecosystem while also advancing widely used capabilities such as VLESS, REALITY, and XTLS Vision. v2rayN and v2rayNG are commonly used to manage Xray configurations. The graphical interface organizes complex fields into forms, but the effective result still depends on the combination of protocol, security layer, transport, and routing parameters, so the server and client must remain consistent.
v2rayN, v2rayNG, and v2flyNG are all maintained as open-source projects, with releases governed by their respective stated licenses. Open development allows the interface logic, configuration handling, and kernel integration to be reviewed over time, while enabling each platform to develop its own workflows around the same protocol concepts. Users should still distinguish the client license, kernel license, and licenses for third-party components.
Client updates typically include interface changes, platform compatibility fixes, configuration-structure adaptations, and changes to kernel integration. Subscription content is maintained by the service provider; updating the client does not automatically correct server-side parameters. When moving to another device, save the subscription source, manual routing rules, DNS setup, and local preferences first, then recheck permissions and system proxy status on the new platform instead of assuming every local setting can be reused unchanged.
